Deodorization is the process of removing or neutralizing unpleasant odors from substances, such as food, air, or materials. This technique is commonly used in various industries, including food processing, where it helps improve the smell and taste of products like oils and fats. Methods of deodorization can include physical processes, like steam distillation, or chemical methods, such as using activated carbon. In addition to food, deodorization is also important in maintaining a pleasant environment in homes and public spaces. Air purifiers and deodorizing sprays are examples of products designed to eliminate odors. Overall, deodorization plays a crucial role in enhancing the quality and acceptability of various items and environments.
